Meysi, a terrier crossbreed who lives in Poland, is only about the size of a soda can. She is 7 centimeters tall, 12 centimeters long, and weighs 250 grams (about nine ounces). Meysi is only four months old, so any world record will have to wait until she is at least one year old. But have you ever seen such a tiny dog? See some videos of Meysi at Laughing Squid. Link
